The arising initial value problems deal with systems of partial differential equations involving Schrödinger like equations, hyperbolic and elliptic equations. Depending on the model -- with Fourier or with Cattaneo type heat conduction -- we obtain polynomial decay rates without or with regularity loss. This way we obtain another example where the loss of regularity in the Cauchy problem corresponds to the loss of exponential stability in bounded domains. The well-posedness is done using semigroup theory in appropriate space reflecting the different regularity compared to the classical single temperature case, and the (optimal) decay estimates are obtained with sophisticated pointwise estimates in Fourier space.</dcterms:abstract> <dcterms:issued>2019</dcterms:issued> <dspace:isPartOfCollection rdf:resource=""/> <bibo:uri rdf:resource=""/> <dcterms:title>The Cauchy problem for thermoelastic plates with two temperatures</dcterms:title> <dc:creator>Racke, Reinhard</dc:creator> <dc:creator>Ueda, Yoshihiro</dc:creator> </rdf:Description> </rdf:RDF>
